This data release for the paper "First eccentric inspiral-merger-ringdown analysis of neutron star-black hole mergers" contains posterior samples for the 3 binary neutron star-black hole merger events analysed, obtained from public GWOSC data with the bilby Bayesian inference package (via parallel_bilby), dynesty nested sampler and a set of waveform models (IMRPhenomTHM, IMRPhenomTEHM). The provided compressed file contains 11 hdf5 bilby posterior files, which can be read easily using bilby standard tools (concretely bilby.read_in_result(file), see bilby docs for details). If you make use of these samples, please cite both this data release and the paper. File list: name structure eventNumber_fref_coordinatesused_sampler_priorormodel_date_nondefaultdetails_merged_result.hdf5 For all cases, fref is set to 20Hz, the coordinates are EOB, and the samplers used are the default by parallel_bilby, except for one case which uses random walk (rwalk). Most of the runs are obtained using IMRPhenomTEHM, allowing for two different priors used for the eccentricity parameter: either "Uni" for uniform, or "LogUni" for log-uniform priors. Additionally, each event includes at least one quasi-circular run using the IMRPhenomTHM (THM) model. Default settings correspond to an initial frequency for the likelihood integration of 20Hz; a duration of 32 seconds for GW200105, 64s for GW200115, and 128s for GW230529; and a starting frequency for the waveform of 17Hz. In the case of GW200105, extra runs were performed varying all these quantities, indicated in the name on the "nondefaultdetails" placeholder. Concretely: 64s indicates a duration of 64s of data. 33band indicates that all (l,m)<= (3,3) are in band at 20Hz, so the waveform starts at 13.2Hz. 25HzL1 indicates that the likelihood integration starts at 25Hz for LIGO Livingston.
